Abstract

SISTEMA DE BOMBA, CAMINHÃO BETONEIRA E MÉTODO PARA CONTROLAR UM SISTEMA DE BOMBA. Um sistema de bomba inclui um circuito de fluído de circuito de fluido de laço fechado incluindo um motor para fazer girar um primeiro componente conectado ao circuito de fluído de laço-fechado. Uma bomba de laço-fechado faz girar o motor até uma primeira velocidade rotacional máxima. O circuito de fluído inclui uma válvula de controle para alternar o fluxo de saída a partir da bomba de laço-aberto. A válvula de controle conecta seletivamente a bomba de laço-aberto ao circuito de fluído de laço-fechado, e simultaneamente desconecta a bomba de laço-aberto do circuito de laço-fechado. Quando a bomba de laço-aberto é conectada ao circuito de laço-fechado, a bomba de laço-fechado e a bomba de laço-aberto fazem girar o motor em uma segunda velocidade rotacional, que é maior que a primeira velocidade rotacional máxima.PUMP SYSTEM, CONCRETE MIXER TRUCK AND METHOD FOR CONTROLLING A PUMP SYSTEM. A pump system includes a closed-loop fluid circuit fluid circuit including a motor for rotating a first component connected to the closed-loop fluid circuit. A closed-loop pump turns the motor up to a first maximum rotational speed. The fluid circuit includes a control valve to switch the output flow from the open-loop pump. The control valve selectively connects the open-loop pump to the closed-loop fluid circuit, and simultaneously disconnects the open-loop pump from the closed-loop fluid circuit. When the open-loop pump is connected to the closed-loop circuit, the closed-loop pump and the open-loop pump rotate the motor at a second rotational speed, which is greater than the first maximum rotational speed.
